Summary
The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to limited file deletion due to insufficient file path validation in the '__construct' function in all versions up to, and including, 2.20.4. This makes it possible for unauthenticated attackers to delete theme files on the server.
Risk Assessment
An attacker could delete theme files, potentially leading to site unavailability or malfunction. The risk is high because exploitation requires no authentication.
Recommendation
Update the Spectra Gutenberg Blocks plugin to a version later than 2.20.4. Until then, consider restricting site access or deploying WAF rules to block suspicious requests.
